Some other prospective cohort study showed a suggestive trend of reduced glaucoma risk with higher intake of folate (vitamin B-9) i.e., compared with the lowest quintile of cumulatively averaged total folate intake, the MVRR of exfoliation glaucoma or glaucoma suspect for the highest quintile (Q5; ≥ 654 μg/day) was 0.75 (95% Confidence Interval [CI]: 0.54–1.04; p for linear trend = 0.02) ( 17 ).
